K-Tec Stealth Exhaust any good?? Also ultimax pads??



  Clio F1 R27
Hi peeps,

My middle section is almost gone and I've just booked it into K-Tec to fit the Stealth Exhaust this saturday.

Can anyone give me any comment on this system? I was looking for some answers to the following questions -

How nice does it sound at higher revs? hehe
I have a long commute to work, is it likely to annoy me at lower revs or is it quite well behaved on long journeys?
Are there any noticable improvements in performance?
How do insurance companies react to that sort of thing being put on your car?

Any other comments would be welcome!

Many thanks,
Steve

not much of a review.... but i've heard the k-tec units are pretty poor. I know there is a few guys on here that has them, and some say they are ok...... but afaik the general consensus is poor quality

Really?

It's alot of money to spend. They've quoted me £460 to replace the exhaust and front and rear pads to the ultimax ones.

If anyone else has any comments it would be appreciated.

I don't want some screaming non standard exhaust which is gonna bump up my insurance loads and annoy me and my girlfriend when we are having a nice trip to the beach or something!! lol If you know what I mean...

If it's not worth it I'll probably just go and get the stock kit...

Help!

Issues with centre box rattling inside, brackets falling off, poor fit and lining up of brackets.

All may be sorted now but ur call!!

It will more than likely be ok but I am not the only one with probs, thats a no bad price if they are fitting pads allround and an exhaust

i think the ktec is fine, although i am on my third centre box in two months (all under the lifetime warranty of course), the latest centre section is the revised version and is doing well.

If your close to ktec (i'm not, 300 miles away), you have no worries. They do have excellent customer service.

heres what it sounds like (with decat):

Good exhaust

I'm sure if they are fitting it they'll do a good job

People complain about fitting etc. but what can you expect from scrotes down at Kwik-fit lol

I love my stealth.

Getting it fitted correctly is vital - some people have had them hanging way too low - hardly stealthy LOL - mines tucked right up out of sight.

They're as loud as you want them to be...bimbling along on a light throttle it's only slightly louder than standard. Give it full throttle at high revs, and it rasps away nicely.

No change to my premium as I convinced them the only reason it was on there is because the standard Renault one is s**t and far too expensive - so stainless was the only way to go, and this K-tec one is the only one without a huge tailpipe.

I've covered about 40k miles with mine on and I think it's more than bearable - you definitely know you've got it fitted, but it doesn't give you a headache.

Sound clip here... it's a bit louder than a standard K-tec stealth due to the decat and the rear of the car being stripped to bare metal.

3 including mine, I have had welds split too but this was only a batch of ten so dont let that put u off!!

Thanks for all this, I'm still not sure. I'm waiting for two quotes for stock kit from renault dealers.

Will it actually give me any increased performance?

Really appreciate the help guys! What a great site this is.

yes it will if you take the cat off as well, then put an induction kit on, then awt inlet manifolds, then get a RS Tuning map. should see about 10-15 bhp.

if you want more get some cams and/or a turbo you could get lots of power.

starts getting expensive though!

sorry, if you just put the exhaust on, then your probably looking at about 1 bhp increase.

I have the revised Mark 2 version.

Had pretty poor fitment the first time but now im 100% happy. K-tec did not fit mine. Got a local firm.

Its holding up as far as reliability and sound are concerned.

Good purchase!

Just had a quote from renault dealer for fitting a stock middle section and pads all around it.

I comes in at over 500 quid! What a rip off.

I'm pretty certain I'm going for the k-tec!!!

Hello guys,

Right, if I could put the record staright on a couple of recent issues with the stealth exhausts.

We had a batch of 20 made a few months ago which had a potential issue with the centre section. It turned out a guy welding the centre boxes was only tacking a pipe within in the centre silencer instead of fully welding around the complete outside of the pipe. This resulted in the weld braking and causing the rattle.

We have changed just about all of these under warranty and all the new ones have been fine since (apart from Deviltronics, that has the weld split on the side of the box which I or Janspeed have never seen before).

Apart from 1 or 2 people on here we have had nothing but good feedback about the revised exhaust, the construction and quality are superb, as is the back up we have received from Janspeed over this issue.

I am very confident to back up the quality of the system and put it up against any others available going on what we have been told by our customers.

Stevo 172 I am sure you will not be dissapointed when you see the system on Saturday and the fact we are fitting will make sure it is spot on.

Iain, I had hoped you had moved on from the shocking version of the Mk1 stealth you received (I will be the first to confirm this). Once we sent it back to the previous manufacturer they replaced it immediately as well as apologised sincerely. The system has moved on since then, please do the same.

I hope this clarifies the situation and if anyone does have any issues with any of our systems please let me know, we are only too happy to help sort out any problems.

David.

Loved my tiger (Ph1) stealth from k-tec! One of the nicest sounding exhausts i heard for an RS.

i bought one simply because it was stainless and cheaper than a standard renault one, its a little loud but not unbearable.....although it does y head in sometimes on long runs (i travel from n.wales to oxford twice a week!!...and *STILL* not been spotted in 4 years of having it!!)

fitted it myself....all seems ok so far!!! if u dont like it, sell it! ;)

I bought one about 4 months ago and fitted it myself (easy job) only problem was that I lost the bolt that secures to the rear mount. probably my fault. Still, mine has been fine and sounds ok too. No rattles welds look ok on mine, however the scorpion zorsts are better build quality but they don't do a stealth. You pays your money and makes your choice!

I have had more mk2 systems than mk1's, All the mk2's had the same fault so I must be pretty dam unlucky to get 2 out of a 20 batch!! (you told me it was10)

Yes I have moaned about the welds on that picture before, but when U look and that pic and realise it was a replacement system you would think u might send one that at least looks good after the first one FELL OFF!!

You forgot to mention the part where u put me onto the manufacturer to sort it out!!

P.S anyone has any probs fitting one give me a shout I have seen it done lots of times.

It did sound s**t hot though, David u were eventually spot on about sorting out issues but I am still majorly out of pocket!!!

I am well happy with the sound and fitment of mine (fitted @GDI) few teething problems but make sure you take it out for a spin with the guy who fits it to listen for any rattles etc so he can adjust accordingly !

Sound clip of mine with Yozza decat !

gotta say my ktec centre section is pretty tough....... the leading edge of my silencer is bent as hell from catching it on a cobbled speed hump and its not split open yet

not overly impressed with the overal quality but it fits and doesnt fall off so good enough :)

I have the K-tec with recessed tip, same system. Cannot fault the quality, they fitted mine, brilliant job and the customer service is great, they really do care, contrary to what you believe on here sometimes....

Oh, and noise wise, it is quiet when you want it qiet, and slightly louder under load, but not chavved nova by any means!
